- SP Performance Diamond Slotted Rear Brake Rotor Set 34147C
Description
Distinctive Style. Elite Performance. Stand out with SP Performance Diamond Slotted rotors. The diamond dimples increase surface area and help the rotor shed heat without drilling through it, while the slots keep the pad surface clean, vent the gases that cause fade at high temperature and channel water away for better wet weather response. Form and function in one rotor. This set covers the rear axle with two rotors in silver zinc coating. Fits 2014-2018 BMW 328d xDrive, 2013-2016 BMW 328i xDrive, 2012-2015 BMW 335i, 2017-2020 BMW 430i, 2017-2020 BMW 430i Gran Coupe, 2017-2020 BMW 430i xDrive, 2017-2020 BMW 430i xDrive Gran Coupe, 2016-2018 BMW 330e and 16 more. SP Performance is a women owned business in Lawrenceburg, Indiana. Our rotors are machined in house on CNC equipment, inspected before they ship, and finished in our ZRC coating in grey, black, silver or red for corrosion resistance and a clean look.
